1.Compact structure 2.High efficiency and energy-savig 3.Full protecting function 4.Reliable operation

 High efficiency &energy-saving

1. Hierarchical capability control: multiple compressors combination can provide multi-stage energy regulation series. Output refrigeration capacity can match the actual load demand. Multiple compressors of varying sizes to match the actual load better, which can achieve the best capacity regulation for load changes, improve efficiency and save energy.

2. Average efficiency of the parallel units is 30% -60% higher than the stand-alone unit varied by the refrigeration systems.

3. Intelligent control system adjusts the number of operating compressor units according to back pressure to maintain the highest efficiency under partial load.

4. Careful design of the pipeline minimizes the pipeline pressure loss, and maximizes unit efficiency.

5. Efficient oil separator almost completely isolates the lubricating oil brought out from the compressor exhaust port to improve the heat exchanger efficiency effectively.

6. Multi-aspirated branches control. If necessary, a unit available for multiple evaporation temperature, the effective use of refrigeration capacity of different evaporation temperature ensures that the system is running in the most energy-efficient work conditions.

Compact structure

1. Compact structure, liquid receiver, gas-liquid separator, oil separator, intercooler, main feed pipe, and electronic control equipment brought together narrows the occupying space and save the room space.

2. Highly integrated design concept to reduce the pipeline, cable consumption, and shorten the construction cycle.
